From: Lower versus higher hemoglobin threshold for transfusion in ARDS patients with and without ECMO
Subgroup analyses of failure-free composites between the lower-threshold group and higher-threshold group in the cohort of patients with ECMO (a) and the cohort of patients without ECLS (b). For each failure-free composite, the cumulative events within 28 days after ARDS onset and the appropriate effect measure (subdistribution hazard ratio [SHR]) with 95% confidence intervals is provided. The SHR has to be interpreted as a chance of the lower-threshold group compared with the higher-threshold group for reaching the particular event (ECMO removal, weaning from mechanical ventilation, stopping sedation, SOFA score < 6, stopping renal replacement therapy, stopping vasopressors) accounting for the existence of the alternative outcome of death. The subdistribution hazard ratio is presented on a log-transformed axis.
